Well I can confirm! i7-2620m will indeed work fine on Toshiba p755s!  It turbos fine and performs well for older hardware! I guess that's about all I can do to this old dinosaur haha.  I should have tested it before the upgrades. oh well haha. I am happy with it so far as the upgrades have at least made it usable!
